摘要:
A method and system of recording successive holograms in a recording medium including a reflective substrate layer, a polarization shifting layer, and a photorecording medium layer is presented. A reference beam and an object beam are propagated at a first direction to a first area of the photorecording medium layer, where the reference beam and object beam have a same first polarization and interfere to produce a first interference grating. The reference beam and object beam are reflected with the reflective substrate layer to be incident the photorecording medium at a second direction, where the reference beam polarization and object beam polarization are altered with the polarization shifting layer to have a same second polarization. The reflected reference beam and object beam interfere to produce second interference grating, with the first polarization and second polarization being different.
